5. Set the pulse width time constraints:
a) For all Trigger When conditions except Outside Range or Inside Range, tap the Time Limit field and use the assigned
multipurpose knob to set the pulse width time condition to meet.
b) For Outside Range or Inside Range conditions, tap the High Time Limit and Low Time Limit fields and use the assigned
multipurpose knobs to set the pulse width time range condition to meet.
6. Tap the Level field and set the threshold value at which you want to measure pulse width.
7. Select the pulse polarity on which to trigger.
Set Trigger Holdoff
Trigger Holdoff sets the time, after triggering on an event, that the instrument waits before detecting the same trigger event to start the next
acquisition.
About this task
Setting the correct holdoff time is important to get a stable trigger. The longer holdoff time for the top waveform causes unstable triggering.
The shorter holdoff set for the bottom waveform only triggers on the first pulse in the burst to remedy the unstable trigger.
Procedure
1. Double-tap the Trigger badge on the Settings bar to open the Trigger configuration menu.
2. Tap the Mode & Holdoff panel.
3. To set a specific holdoff time, tap Holdoff and use the assigned multipurpose knob to specify a holdoff time. Or double-tap the field and
use the virtual keypad to enter a holdoff time.
